Illinois Area Codes Pieces Of Information

Illinois is a state located in the Midwestern United States. As of 2010, the state has a population of 12,830,632 people. The state covers an area of 153,990 square kilometers. Illinois is divided into 102 counties and contains 1,299 incorporated municipalities. The largest city in Illinois is Chicago with a population of 2,695,598 people. The capital city is Springfield with a population of 116,250 people.

If you live in Illinois, then you are familiar with the area codes 217, 309, 312, 618, 630, 708, 773, 815, and 847. These are the ten digits that make up the phone numbers for the state of Illinois. The 708 area code covers Cook County and the surrounding suburbs. The312 area code covers downtown Chicago. The 815 area code covers the northwest Chicago suburbs and the Rockford area. The 630 area code covers the west and southwest suburbs of Chicago. But have you ever wondered about the meaning behind these numbers?

The first two digits of an area code are known as the Numbering Plan Area (NPA). The NPA is also commonly referred to as the area code. The next three digits are known as the Central Office Code (COC). The COC is also sometimes called the prefix. The final four digits are known as the station number and are assigned to individual telephone lines or services.

The NPA was created to designate geographic areas for telephone service. The COC was then used to identify a specific central office within that area that would provide service to that particular geographical region. The station number was assigned to an individual customer line or service connected to that central office.

When looking up information about Illinois area codes, there are a few key pieces of information that you will want to keep in mind. Over time, the use of area codes has changed and they are no longer solely based on geography. The NPA is now used to designate a specific numbering plan such as toll-free numbers, 800 numbers, 888 numbers, etc. The COC is still used to identify a particular central office but may be located anywhere in the world. The station number is still assigned to an individual customer line or service but can be any combination of digits.

Despite the changing use of area codes, they are still an important part of our telephone system and are necessary for making and receiving calls. However, by keeping these key pieces of information in mind, you can be sure that you will have all of the information that you need to make an informed decision about your own area code needs. So the next time you see a string of ten digits on your phone screen, you’ll know that it’s an Illinois area code and you can be proud to be from the Land of Lincoln!
